By: Ben Ruchte, Steve Gressler, and Clark McDonald Properly inspecting plant piping and components for service damage is an integral part of proper asset management. High energy systems constructed in accordance with ASME codes require appropriate inspections that are based on established industry practices, such as implementation of complimentary and non-destructive examination (NDE) methods that […]
By: Edward Dougherty Has the heat conversion efficiency of your heat exchangers degraded? Is the flow of your cooling water system being impeded? Are you repairing or replacing equipment due to localized corrosion causing through-wall failure? Inefficiencies and equipment failures are big problems in any industrial process, but the cause of the problem may be […]
By: StevenBiles and Scott Riccardella A new program to help pipeline operators implement the Material Verification requirements in recently released pipeline regulation (Mega Rule) On October 1, 2019, the Pipeline and Hazardous Materials Safety Administration (PHMSA) published the long-awaited Mega-Rule (Part 1). One of the major new requirements identified in these amendments is when missing […]
By: Vick Nazareth and Bill Lyon The Pegasus code is a culmination of nuclear fuel behavior knowledge and experience that spans a period of over five decades. It is a total fuel-cycle simulation of fuel response from initial insertion in reactor to deposition in permanent storage. The goal of Pegasus is to treat, with equal […]
By: Ben Ruchte It is well known that conventional coal-fired utility boilers are cycling more today than they ever have. As these units have shifted to more of an ‘on-call’ demand they experience many more cycles (start-ups and shutdowns, and/or significant load swings) making other damage mechanisms such as fatigue or other related mechanisms a […]
By: Scott Riccardella, Bruce Paskett, and Andy Jensen On October 1, 2019 the Pipeline and Hazardous Materials Safety Administration (PHMSA) published amendments to 49 CFR Parts 191 and 192 in the Federal Register issuing Part 1 of the Gas Transmission Mega-Rule1. This new regulation is commonly referred to as the Mega-Rule, as it represents the most […]
By: Wendy Weiss Superheater/reheater fireside corrosion is also known as coal ash corrosion in coal fired units. MECHANISM Coal ash corrosion generally occurs as the result of the formation of low melting point, liquid phase, alkali-iron trisulfates. During coal combustion, minerals in the coal are exposed to high temperatures, causing release of volatile alkali compounds […]
San Jose, CA, February 4, 2020 – Structural Integrity Associates, Inc. (SI) announced today the appointment of Mark W. Marano as President and Chief Executive Officer, effective February 10, 2020. Marano succeeds Laney Bisbee following his retirement in late 2019. Marano joins SI following a brief retirement from Westinghouse Electric Company, where he previously was […]
By: Christopher Lohse There have been several industry initiatives to support optimization of examination requirements for various items/components (both Class 1 and Class 2 components) in lieu of the requirements in the ASME Code, Section XI. The ultimate objective of these initiatives is to optimize the examination requirements (through examination frequency reduction, examination scope reduction, […]
By: Jacob Arroyo You’ve just completed the first in-line inspection (ILI) of a new pipeline asset. The ILI tool results are in, and there are no required repairs! However, how sure are we of the accuracy of the results? Could the tool have under-called some of the reported anomalies? Are there any regulatory requirements beyond […]
